CONSTANTS
This section describes constants.
25.1
Decimal Constant (K)
Use this type of constants when specifying decimal data in a program. Specify the decimal constant using K  character (e.g.
K1234). The specification range depends on the argument data type of the instruction using the decimal constant as shown in
the following table:
25.2
Hexadecimal Constant (H)
Use this type of constants when specifying hexadecimal data in a program. Specify the hexadecimal constant using H 
character (e.g. H1234). To specify data in BCD, specify each digit of hexadecimal value with numerical characters 0 to 9. The
specification range depends on the argument data type of the instruction using the hexadecimal constant. The range is H0 to
HFFFF for 16-bit data size, and H0 to HFFFFFFFF for 32-bit data size.
